DISPENSING TANK.

Application filed April 9, 1924, Serial No. 705,180. Renewed November 6, 1928.

The invention relates to means for delivering liquid from tanks, and has for a particular object to provide a safety gasoline truck tank for operation in cities. Insteadof the usual piping leading from bottom outlets to dispensing faucets at the rear of such a tank, subject to breakage in event of collision, with consequent danger of spilling the highly inflammable contents upon the. street, I provide pipes extending from near the bottoms of the compartments upward through the top and thence downward at the side, so that the bottoms of the compartments are closed, and in connection with these pipes I provide a pump and delivery unit movable along the side of the tank vehicle and connectible with the outer ends of the pipes at will. A valved passage across the inlet and the outlet of the pump is opened when the flow has been initiated by operation of the pump so as to cause the delivery to continue by siphon action. Other objects and features of the invention will become apparent as the specification proceeds.

In the accompanying drawings forming part hereof:

Fig. 1 is a side elevation of a vehicle tank embodying the invention;

Fig. 2 is an end elevation with a portion broken away and sectioned; and

Fig. 3 is a detail sectional View through the air-vent valve, taken on a larger scale.

The vehicle and frame are sufliciently illustrated by the wheels 2, the longitudinal sills 3, the cradle bolsters 4 and the runningboards 5, 6 at opposite sides of the lower part of the tank. I

The tank comprises a plurality of separate compartments 8 (three being shown) of definite capacity, and is secured to the cradle bolsters by straps 9.

Each compartment has a depressed pocket 10 in its bottom, in which is located. the lower, inlet end of a pipe 11, there being one of these pipes for each compartment. The said pipes pass upward throughthe interiors of the compartments and through suitable stufling-boxes 12 in the tops of the compartments, and their outer portions 13 are carried down at one side of the tank, terminating at the same level in connection-ends 14.

Shut-0ft" valves 15 are placed in the outer limbs of the pipes, and at their highest points are air-vent valves 16 having springs 17 acting to open them. Depending pull connections 18 terminating in rings 19 enable the vent valves to be closed conveniently.

A delivery unit 20 is mounted with rollers 21 to travel forward and rearward in guides 22 on the running-board 5. This unit includes a rotary pump 23 operatable by a hand-crank 24, and having inlet and outlet pipes 25, 26 which extend laterally from a direct-flow pipe or passage 27. The inlet end of the pipe 27, above its junction with the inlet pipe 25 to the pump, is provided with a coupling 28 adapted to connect the pipe 27 in line with any one of the limbs 13. The outlet end of the pipe 27, below its junction with the outlet pipe 26 from the pump, is provided with a terminal 29 adapted to receive a hose 30 for insertion in the underground tanks into which deliveries are made. A shut-off valve 31 is placed in the passage 27 between the inlet and the outlet of the pump.

The valves 15 are normally closed and the vents 16 are normally open. In order to deliver the contents of the left-hand end compartment of Fig. 1, with which the delivery end is' shown connected, the corresponding valve 15 is opened and the chain 18 is pulled down and its ring caught on a hook 32 on the delivery unit, thereby holding the corresponding vent closed against,

the action of its spring. The valve31 is closed. The handle of the pump is then turned a sufiicient number of times to lift the liquid up through thepipe 11 and over the top of the siphon. When the outflow through/ the delivery limb has started,

pumping is stopped and the valve 31 is opened. The liquid then siphons out of the compartment. The flow is stopped by permitting the vent to open, breaking the siphon, or by closing the valve 15. In case only part of the compartment load is deliv-v ered at one time, opening of the ventinsures against accidental siphoning of the remaining contents should the valve 15 be thereafter opened.

While the preferred embodiment of the invention has been described I do not necess'arily limit myself thereto, since details are subject to modificationand the invention or parts thereof may be employed in other applications.

- What I claim as new is:

1. In a vehicle tank, the combination with a series of tank compartments and pipes having their inlets near the bottoms of the compartments'and thence extending upward through the upper walls, passing outside the compartments and terminating in a series of connection ends substantially in line, of a way alongside the compartments and a delivery unit movable along said way and including a pump and means for connecting said unit at will with the connection ends of the pipes of the several compartments.

, 2. In a vehicle tank, the combination with a series of tank compartments and pipeshaving their inlets near the bottoms of the compartments and thence extending upward through the upper walls, passing outside the compartments and terminating in a series of connection ends substantially in line, of a way alongside the compartments, a pump and delivery unit movable on said way, and means for connecting the same at will with the connection ends of the pipes of the several compartments.

3. In a vehicle tank, the combination with a series of tank compartments and pipes-having their inlets near the bottoms of the compartments and thence extending upward through the upper walls, passing outside the compartments and terminating in a series of connection ends substantially in line, of a way alongside the compartments, and a delivery unit movable along said way and including a pump and means for connecting said unit at will with the connection ends of the pipes of the several compartments, said delivery unit having two passages included between its inlet and outlet, one of said passages containing a pump, and the other passage being adapted to be opened to permit the flow established by the pump to continue by siphon action.

4:. In a vehicle tank, the combination with a series of tank compartments and pipes having their inlets near the bottoms of the compartments and thence extending upward through the upper walls, passing outside the compartments and terminating 1n a series of connection ends substantially 1n line, of a way alongside the compartments, and a delivery unit movable along said way and including a pump and means for connecting said unit at will with the connection ends of the pipes of the several compartments, said delivery unit comprising an inlet adapted for connection with said connection ends, an outlet adapted to receive a hose, a loop passage containing a pump, and a direct passage containing a valve for opening and closing it.

5. In a vehicle tank, the combination with a series of tank compartments and pipes having their inlets near the bottoms of the compartments and thence extending upward through the upper walls, passing outside the compartments and terminating in a series of connection ends substantially in line, of a way alongside the compartments, and a delivery unit movable along said way and including a pump and means ,ior connecting said unit at will with the connection ends of the pipes-of the several compartments, said delivery unit having two passages included between its inlet and outlet, one of said passages containing a pump, and the other passage being adapted to be opened to permit the flow established by the pump to continue by siphon action, together with means for breaking the siphon.

6. A tank compartments, pipes having their inlet ends near the bottoms of the several compartments and thence extending upward through the upper walls, passing outside the compartments and terminating in connection ends substantially in line, a way alongside the tank compartments, and a delivery unit including a pump movably mounted on the way and connectible at will with the connection ends of the several compartments.
